We have included some questions that are repeatedly asked in exams !!!

**What is the area of a right angle triangle ?**

I.The base of a triangle is 12cm

II.The height of a triangle is 19cm

III.The hypotenuse of the triangle is 25cm

1.Only I is sufficient

2.Only II is sufficient

3.Only III is sufficient

4.Any two of the three are sufficient

5.None of these

Answer -4.Any two of the three

**Explanation :**

Area = ab/2

From hypotenuse and one side we can find other side of the traingle

**What is the rate of interest per annum ?**

I.An amount double itself at SI in 10 years

II.The difference between SI and CI on an amount of Rs.20,000 in 2 years is Rs.200

III.The CI accured in 8 years is more than the amount.

1.Either I or II is sufficient

2.Both I and II are sufficient

3.Both II and III are sufficient

4.Either I or III is sufficient

5.None of these

Answer –**1.Either I or II is sufficient**

**Explanation :**

From I :

Principal = P, Amount = 2P

Interest = 2P – P = P

SI =P = P*R*10/100 => R = 10%

From II

R = (200/20000)^{1/2}* 100 =10%

**What is a two digit number ?**

I.The sum and the difference of the digits are 12 and 5 respectively

Answer –**5.If the data in both the statements I and II together are necessary to answer the question.**

**Explanation :**

X+y = 12

x-y = 2

solve this 2 Equ u will get the value of X and Y and also that no should be divsible by 5

Answer –**3.If the data either in statement I alone or statement II alone are sufficient to answer the question.**

**Explanation :**

From I =>1,50,200*112/100*112/100

From II => 2*98,000

**What was the % of discount given on the marked price of a Refrigerator ?**

**1.**If the data in statement I alone is sufficient to answer the question.

**2.**If the data in statement II alone is sufficient to answer the question.

**3.**If the data either in statement I alone or statement II alone are sufficient to answer the question.

**4.**If the data given in both I and II together are not sufficient to answer the question.

**5.**If the data in both the statements I and II together are necessary to answer the question.

Answer –**1.If the data in statement I alone is sufficient to answer the question.**

**Explanation :**

CP = 17650*100/110 = 16045

MP = 16045*125/100 = 20,056

% = 20,056-17650/20,056 *100 = 12%

**What is the speed of the car ?**

I.The bus takes 2hrs more than the train to cover a distance of 220km

II.The car moves 17kmph faster than bus

**1.**If the data in statement I alone is sufficient to answer the question.

**2.**If the data in statement II alone is sufficient to answer the question.

**3.**If the data either in statement I alone or statement II alone are sufficient to answer the question.

**4.**If the data given in both I and II together are not sufficient to answer the question.

**5.**If the data in both the statements I and II together are necessary to answer the question.

Answer –**5.If the data in both the statements I and II together are necessary to answer the question.**

**Explanation :**

Time taken by bus = t+2hrs

Speed of the car = S+17

D = 220km

S = 220/t+2

S+17 = 220/t

Equate this two to find the speed

**What is the area of the circle ?**

I.The diameter of the circle is 70cm less than its cicumference

**4.**If the data given in both I and II together are not sufficient to answer the question.

**5.**If the data in both the statements I and II together are necessary to answer the question.

Answer –**1.If the data in statement I alone is sufficient to answer the question.**

**Explanation :**

D = 2r

2*3.14*r – 70 = 2r

2*3.14*r – 2r= 70

2r(6.28-1) = 70

R = 70/10.56 = 6.6

Area = 3.14*6.6*6.6

**The age of A and B are in the ratio of 5:8, what is the age of A ?**
